purple tang and powder blue tang?

[Johnny Reefer]

I agree also.
I know my situation involves a PB and a YT, (not PT), but FWIW the PB and YT were QT'ed together, and introduced to the main tank together, and not once have I seen a millisecond of aggression from either fish toward the other. Like I said, they are best of buds, and spend most of ther time hangin' out together.

Cheers,
